Personal Effects

I was at a golden wedding anniversary event the other week (congratulations Sue and Mike) and happened to be in their back garden when their granddaughter looked at the watch on her wrist and said “There is someone at the front door”. How did she know this? She explained the details.

So when I got this week’s topic of Personal Effects I started to wonder if there could be a system called ‘Personal effects’ such as in email as one of the definitions of Personal Effects is things that you take with you.

Now that could cover a multitude of stuff but I’d like to take the opportunity to look at how medical technology has and might affect us. I’m taking the invention of wearable spectacles in Venice during the 13th Century as my starting point for how it has assisted human beings in our everyday lives. 

A brief run through includes pocket watches in around 1590, wearable hearing aids in the late 1800s and in 1949, American biophysicist Norman Holter invented the first portable health monitoring device. And that is about it for personal devices. I’m not counting things like stethoscopes which are used by medical professionals.

Things changed with the development of electronics. We can see this in smart watches used, for instance, in counting steps, in portable measuring devices for various bodily functions, in implanted devices.

But what about future developments. The website techtarget suggests:
Wearable technology is becoming increasingly popular and is set to revolutionize the future. While fitness trackers, smart devices, intelligent clothing and VR and AR headsets have gained widespread approval, the full potential of these technologies has yet to be realized.

The following are some futuristic concepts tech experts have predicted will shape wearable technology:
Energy harvesting. One drawback of wearable technology is that it must be taken off for regular charging. 

Energy harvesting is being researched and could prolong battery life by converting body heat, movement or solar energy into power. Piezoelectricity is one example of energy harvesting where piezoelectric ceramic can convert the body vibrations produced during movement into energy.

Smart contact lenses that contain microscopic sensors could directly cover and move with the human eye introducing the possibility of far more sophisticated capabilities than smart glasses.

AI integrated sensors that help with performing functions associated with thinking are currently being developed. Brain implants that could help people recover from traumatic brain injuries, alleviate mood disorders and assist those with communication disorders.

I was particularly taken with epidermal electronics which because of their mechanical properties resembles that of skin. With this inherent ability epidermal electronics can accurately acquire data without altering the natural motion or behaviour of skin. The thin, soft, flexible design of epidermal electronics resembles that of temporary tattoos laminated on the skin. Essentially, these devices are ‘mechanically invisible’ to the wearer.

And how much more personal and effective is that.

This poem was published in a Poetry Anthology, organised by Christabel Hopesmith, called 'Body and Soul ', to mark 70 years since the start of the NHS. I’m including it as it covers some of the above from both a technological and personal point of view.

It’s never finished

Over a coffee
I wrote up the job.

Replaced ECG lead.
Tested ok. Informed Staff Nurse.

and that was that
which didn’t seem enough
considering
so I added the Staff Nurse’s name
and doodled
an arrow tipped wire
threading my lines
into a cartoon heart
which seemed appropriate
for the Cardiac Catheterisation Suite

and dunked a biscuit

wondering whether
if I’d been the patient
would I be disturbed
by some jerk
trying to chat up a colleague
by reciting the reasons
why platinum was used
in the guide wire
about to go into my heart

or would I give a damn
as long as it was obvious
they knew what they were doing
as long as I knew I’d get back
to family and friends

and if I was that patient
would I have helped the jerk
by saying that platinum
was also an anniversary
so why not celebrate the NHS
by taking someone to dinner

I finished the coffee
and wished I’d thought of that.

Thanks for reading, Terry Q.
